| Determination of destructiveness for subvertical coal-bed by radiolocation technology. Georadar GROT-12.
Figure 1. Radarogram under layer along open-cast mine road.
Figure 2. Photo of coal-bed with line of georadar profile (several meters offsetting of vertical lines is possible because this photo was taken
in the opposite side of open-cast mine with angle 30° and distance about 1 km).
The technology allows estimate the degree of destructiveness for productive coal-bed, define tectonic zones of different sizes in such adverse geological
and geophysics conditions as presence of steep hade for rock layers, minimal specific electrical resistance (SER), big number of rumpled folds.
